  1. The Step 1 analysis included significant fixed markers of risk; In the Step 2 analysis significant internalizing (depressive, anxiety and posttraumatic stress) symptoms were added to the variables included in Step 1; The Step 3 analysis added significant externalizing symptoms (conduct problems and delinquent behaviour) to the variables included in Step 2; The fully adjusted Step 4 analysis added affiliation with delinquent peers (i.e., how many of their friends were involved in risk taking behaviours) to the variables included in Step 3
